Three classmates spent a total of $56. Anna spent $5 more than Julie and Eva spent $7 more than Anna.
- How much money did Julie spend?
- How much money did Eva spend?
(a)
Amount that Julie spent = 1 u
Amount that Anna spent = 1 u + 5
Amount that Eva spent = 1 u + 5 + 7 = 1 u + 12
Total amount that they spent
= 1 u + 1 u + 5 + 1 u + 12
= 3 u + 17
3 u + 17 = 56
3 u = 56 - 17
3 u = 39
1 u = 39 ÷ 3 = $13
Amount that Julie spent
= 1 u
= 13
(b)
Amount that Eva spent
= 1 u + 12
= 13 + 12
= $25
Answer(s): (a) $13; (b) $25
